when i first got my crs a little over a yr ago i had them all in the same tank. in feb i got some fss and move all i could catch to that tank with the lower ph. now i have 2 tanks going with the original shrimp i have never added any new shrimp to either tank. funny thing is i was lookin in the tank in my room the other day and the eggs on them are kinda orange like tiger shrimp eggs. the ones in the small tank in the computer room have red eggs. any one know why they would be 2 different colors? i do know the one with red eggs has red leggs so could that have something to do with it? i will get pics when i see them again
